Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 and 2, the utility model discloses but locking regulation vaulting pole includes cylindrical sleeve 1, the suit is at piston rod 2 in sleeve 1, with 2 coaxial coupling's of piston rod telescopic link 3, and suit torsion spring 4 and switch 5 on the piston rod in proper order, torsion spring 4's inner wall is laminated on piston rod 2 closely, with locking piston rod 2, the restriction piston rod is upper and lower to slide, torsion spring 4's one end fixed mounting is on sleeve 1, the other end supports and leans on in switch 5, torsion spring 4 loosens piston rod 2 under switch 5's toggle action.

Above-mentioned switch 5 has seted up fluting 12 including the installation cover 51 of suit on piston rod 2 and integrated into one piece plectrum 52 on installation cover 51 outer lane on sleeve 1, makes switch 5's plectrum 51 stretch out from fluting 12, and convenient to use person operates, toggle switch, and the notched setting still can limit switch's toggle distance, plays limiting displacement.

Torsion spring 4 is 2, and 2 torsion spring 4 symmetry set up in switch 5 both sides to increase the locking force, make its maximum article that can support 2 tons.

A plurality of mounting holes 11 for mounting the torsion spring 4 are uniformly formed in the sleeve 1, the mounting holes are mounted at the same height and are uniformly distributed on the wall of the sleeve, and a mounting part 41 at the end part of the torsion spring 4 can be mounted in any mounting hole so as to pre-tighten the torsion spring and ensure that the torsion spring is tightly attached to the piston rod, thereby realizing the locking of the piston rod; the pre-tightening force of the torsion spring can be adjusted by installing the end part of the torsion spring in different installation holes, so that the supporting force is adjusted.

The lower extreme integrated into one piece of telescopic link 3 realizes that the telescopic link is connected with the piston rod ground in the upper end of piston rod 2, when ordering about the piston rod up-and-down motion, also drives the telescopic link and carries out concertina movement.

A first positioning boss 6 is integrally formed at the joint of the telescopic rod 3 and the piston rod 2, is cylindrical, has an outer diameter slightly smaller than the inner diameter of the sleeve, plays a role in limiting, avoids the piston rod from deviating during sliding, avoids the phenomenon of clamping, and also plays a certain role in protecting the torsion spring; this first location boss 6 sets up in top torsion spring ground top, plays limiting displacement, avoids the telescopic link to follow torsion spring and switch roll-off, guarantees the normal use of adjusting the vaulting pole.

The lower extreme threaded connection of piston rod 2 has a second location boss 7, and this second location boss 7 can be the nut, and threaded connection sets up in below torsion spring's below on the piston rod, plays limiting displacement, avoids the telescopic link to follow torsion spring and switch roll-off, guarantees the normal use of adjusting the vaulting pole.

The upper end of the telescopic rod 3 is provided with a U-shaped mounting seat 8, and the U-shaped mounting seat 8 is sleeved on the telescopic rod 3 so as to realize fixed connection with a supporting object; realize the location installation of U type mount pad 8 through two nuts, the equal threaded connection of these two nuts is at the telescopic link to set up respectively in the upper and lower extreme of U type mount pad.

At ordinary times, the torsion spring is in a pre-tightening state, namely the inner diameter of the torsion spring is reduced, and the inner wall of the torsion spring is tightly attached to the piston rod so as to lock the piston rod, namely the piston rod is locked at ordinary times, so that the piston rod cannot slide up and down, and the position of the telescopic rod cannot slide up and down; during the unblock, toggle switch forces torsion spring rotatory, makes torsion spring's internal diameter grow, and torsion spring loosens the piston rod, makes the piston rod drive telescopic link upper and lower slip to the distance that the telescopic link stretches out the sleeve outside is realized to the flexible of telescopic link, when transferring required position, only needs to let the switch of let go up, and the initial position is replied under torsion spring's restoring force effect to the switch, lets torsion spring locking piston rod again. The utility model has the advantages of simple structure, convenient operation and large locking force.

Finally, it should be noted that: the above embodiments are merely illustrative of the technical solutions of the present invention, and not limitative thereof; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
